Last week I tried to install Honkai Star Rail on my old Android phone only to get a pop-up saying I had insufficient storage, even after deleting three unused apps and half my photo album. That’s when I decided to dig into exactly how much gigabytes does Honkai Star Rail take across every platform, plus workarounds for players who don’t have tons of extra space on their devices. Whether you’re a new player getting ready to download for the first time or a long-time fan wondering why your storage keeps disappearing after every patch, this guide covers all the numbers you need to know, plus easy tweaks to free up space without breaking your game.
How Much Gigabytes Does Honkai Star Rail Take on PC, Mobile, and Console?
I tested the install size across three devices earlier this month to get the most accurate current numbers, so you don’t have to guess before you hit download. For Windows PC, the base game install sits at roughly 28 GB if you only download one voice pack and skip optional high-resolution assets. If you opt for all available language packs and 4K cutscene assets, that number jumps to between 35 and 38 GB total. You’ll also want to leave extra space for future patches, which usually add 2 to 4 GB each for major version updates.
For mobile users, the size varies slightly between operating systems. Android devices need 18 to 22 GB of free space for the base install, while iOS users need 20 to 24 GB. The difference comes down to how each operating system compresses game assets, and you can expect that number to go up by 1 to 3 GB after your first login as the game downloads additional resource files. For PlayStation 5 users, the base install is 32 to 36 GB total, with all default language packs included automatically, so you don’t have to worry about extra downloads after the initial install.
Keep in mind these numbers are for the latest available version of the game. If you’re re-installing after a year away, you might see a slightly larger size because HoYoverse adds new maps, characters, and event content every six weeks. You should always leave at least a few extra GB of free space beyond the listed install size to avoid installation errors.
What Takes Up the Most Space in Your Honkai Star Rail Install?
If you’ve noticed your game size growing faster than you expected, you’re not alone. I checked my own install last week and found it had gone up by 8 GB in the past six months, even though I never downloaded any extra content. Most of the space is taken up by mandatory game assets you can’t remove, but there are a few non-essential files you can delete to free up space quickly. The biggest storage hogs in your install are:
I was shocked when I first checked my resource usage and found that I had all four voice packs installed, even though I only ever use the Japanese dub. Deleting the other three freed up almost 4-6 GB of space immediately on my phone, which was enough to install the next update without deleting any other apps. The only files you can’t remove are the core game assets and cutscenes, so you don’t have to worry about breaking the game when you delete unused resources.
Easy Tips to Reduce Honkai Star Rail Storage Usage Without Losing Progress
You don’t have to delete the entire game to free up space if your storage is running low. These simple tweaks take less than five minutes to complete, and none of them will impact your gameplay or delete your saved account data. The first thing you should do is delete any unused voice packs. You can find this option in the game settings under the “Resources” tab, where you can see exactly how much space each language pack takes up before you delete it.
Next, clear your game cache regularly. Temporary cache files build up over time as you play, and they can take up 1 to 3 GB of extra space after a few months of regular play. You can clear the cache directly from the in-game settings menu, and it won’t delete any of your saved progress, screenshots, or custom settings. If you’re on mobile, you can also skip the optional high-resolution asset download when you first install the game. These assets are designed for high-end flagship phones, and most players won’t notice a visual difference on smaller screens, but they take up 3 to 5 GB of extra space.
Finally, avoid saving too many screenshots and video clips directly to the game’s internal storage. You can move these files to your device’s cloud storage or an external drive to free up extra space on your main drive. None of these tweaks will impact your gameplay performance or delete your saved progress, so you can test them out without worrying about losing your 5-star characters or quest progress.
What to Do If You Don’t Have Enough Storage for the Latest Update
Sometimes even after deleting unused voice packs and clearing your cache, you still might not have enough space for a major new update. That’s a common problem for players with older devices that only have 64 GB of total storage, but there are a few easy fixes you can try before you give up and uninstall the game. If you’re on mobile, you can offload unused apps instead of deleting them entirely. On iOS, offloading keeps your app data but deletes the app itself, freeing up several GB of space for the update, and you can re-download the app later if you need it. On Android, you can move other non-essential apps to an SD card if your device supports it, to free up internal storage for Honkai Star Rail.
If you’re on PC, you can move the entire game install to a different drive with more space instead of re-downloading it. Most launchers let you change the install location in settings, and the process takes less than 10 minutes to complete without any file loss. If all else fails, you can temporarily delete old files you don’t use anymore, like downloaded movies, unused apps, or old game installs you haven’t played in months.
One important thing to remember: always make sure you have at least 10 GB of extra free space before you start downloading a major update. If you run out of space mid-download, you can end up with corrupted game files that force you to re-download the entire game from scratch, which will take even more time and data.
At the end of the day, knowing how much gigabytes does Honkai Star Rail take for your specific platform can save you a ton of frustration when you’re getting ready to install or update the game. The numbers will keep going up as HoYoverse adds new content, but the simple tweaks we covered here can help you keep storage usage under control even as the game grows. If you’re still running into storage issues after trying these tips, you can always check the official game website for the latest install size numbers before you download the next patch.
